Brits go without coal for electricity for the first time since the dawn of the Industrial Revolution.
It's a shell game folks, coal doesn't "expire". As long as it's in the ground, it can be used. All that has been accomplished with this "War on Coal" is that the stuff is essentially in storage. But only in certain places. Other nations are still mining and burning as they always have. As western nations back away from coal they also back away from the very innovations we should be encouraging such as gasification and CO2 sequestration. While there is no such thing as "clean" coal, there is no such thing as clean combustion either. Methane isn't clean, especially when it is burned with atmospheric air, which is primarily nitrogen. Anything that uses air to burn fuel is creating nitrogen oxides and carbon monoxide. The real shame is that we have made amazing strides with energy efficiency since the 70s. Light bulbs used to put out 80% heat and 20% light, now they're like 90% light and 10% heat. I've managed to cut the power and gas requirements of our home in half since 2002 (though oddly, the bills aren't quite 50% lower, thanks to steady taxes and "fees"). All I'm saying is that coal isn't gone. Don't celebrate its demise, it's just on hold. As we burn through oil and gas, largely as a result of population growth, we'll eventually be "forced" to return to old fashioned means and coal is one of them. Renewables could make a better impact but they have become political. The most obvious example of this is the sheer size of today's wind turbines. Why are they so massive? A better plan would be to put up millions of smaller ones even at the residential level. BUT, we have an infrastructure that "needs" lots and lots of power plant workers and they need large rotating equipment to work on. (Yes, I'm speaking to unions, an old fashioned concept that has failed to modernize).
Only because the fossil fuel industry and their supporters don't want them. The reason why wind turbines are large: 1. ...the energy that a wind turbine can harness is proportional to the cube of the velocity of the wind. This means that if we double the wind speed, the power increases eightfold. Since the wind speed is significantly higher as you move up into the upper atmosphere, you will get major power increases from building your windmill higher up. This explains the height. ~ 1 2. The energy from a wind turbine is proportional to the area that the wings sweep out, doubling the radius increases the power by a factor of 4. ~ 1 3. Whether you build a large windmill or a small windmill, the components such as the drive train and the installation and repair will all be pretty close to the same. I mean if you double the size, it will cost more but it won’t cost twice as much. So if you have 10 square miles of land you would rather build 20 large windmills than 100 small ones. ~ 1 4. Transportation, setup, and maintenance is less for one large turbine that puts out the same amount of power as several smaller ones.
Electricity comes from many sources, hydroelectric dams, coal , oil , and natural gas fired generation plants, nuclear reactors , geothermal heat, solar cells, and wind generators mainly. There is also biomass, chemical, piezo, hydrogen, tidal, and wave.
Remembering the furor when Prime Minister Margaret Thatcher closed the coal pits. Do we owe her an apology?
If she'd done it for environmental reasons we might. But she didn't. It was done purely for political ends, mainly getting rid of of the Mineworker's union who had grown very powerful. Their strike brought down the previous conservative govt. under Ted Heath, and Maggie wanted revenge. Still, be glad to see the end of coal.
